WINDOW-SCREEN.

Specification of Letters Patent.

Patented A11 18, l lld.

Application filed January 17, 1914. Serial No. 812,813.

To (ZZZ whom it may concern Be it known that I, PYwnLL VINCENT, a citizen of Canada, and subject of the King of Great Britain, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Window-Screens, of which the following is a specification, reference be ing had therein to the accompanying drawing.

This invention relates to window screens, more particularly of the slidable type, and has for its object the provision of a screen furnished with improved instrumentalities enabling the same to be readily attached to or detached from the usual window casing, and more specifically the invention comprises suitable guiding means adapted to be fixed to a window casing and devices carried by the screen having an interfitting relation with said guiding means to cause a retention or release of the screen from the window casing by a simple shifting movement of the screen with reference to the guiding means, thus dispensing withspecial locks or latches.

The preferred embodiment of the invention, made in keeping with the foregoing objects, includes a pair of guide flanges arranged along the side rails of a window casing, and a screen having a suitable frame adapted to bear against said flanges, associted with guiding and retaining fingers or clips carried by the screen frame adapted to slidably engage the opposite face of the flanges, the flanges being provided with open portions permitting the lateral withdrawal of the fingers or clips therethrough when brought to registering position to release the screen from the casing; and one of the clips being of a springy nature, adjustable to create a frictional engagement thereof with the guide flanges suflicient to hold the screen inadjusted positions vertically of the casing; the upper and lower edges of the fingers or clips or the upper and lower edges of the open portions of the guide flanges or both, as the case may be, being deflected or beveled slightly out of the true vertical plane of the guide flanges to normally facilitate the riding or" the fingers or clips over the said open portions when the screen is in working combination with the casing, and compelling lateral forcible deflection of the screen frame to cause the passage of the clips or fingers through the openings of the guides while the screen is being removed.

I have illustrated the above mentioned embodiment of the invention in the accompanying drawings forming part hereof, and improved details in the construction and arrangement of parts will be apparent from an inspection of such drawings in connection the guide clips carried thereby, showing the,

relation of the same to the guides at the sides of the window casing; Fig. 4 is a horizontal sectional view through the lower clip showing the means for adjusting the same, Fig. 5 is a. vertical sectional view showing by dotted lines the various positions of the screen with reference to the guides during the removal of the screen from the casing, and Fig. 6 is a horizontal section through one side of the window casing looking down upon the top of the screen, and Fig. 7 is a detail vertical sectional view through one of the guide fingers looking toward its guide flange.

Referring more specificall to the drawings, A represents an ordinary window casing provided with the usual lower and upper sliding sashes B and C working in suitable runways formed in the casing.

D is a slidable screen formed of any suitable material conveniently wood, as shown in this instance, the same being adapted to be fitted to the window casing in an out-side position relative to the sliding sashes, the window casing being provided with a suitable, im oroved simple type of guide to that end. T ese guides are constituted by single flanges E projecting outwardly at right angles from an integral flat base F screwed or otherwise secured to the projecting part a of the casing A, as indicated at G, the

guide members thus defined being preferably1 formed of sheet metal. The upper rail cl of the screen frame D is rabbeted at its opposite ends, as at d to receive guide fingers or clips H secured in the rabbeted portions by devices it the rabbets being deeper at the side edges of the sash so as to leave a space 0 between the rail D and the projecting portion of the guide finger H for the reception of the guide flange E. Below the clips H I provide clips or guide fingers I secured to the side rails d of the screen frame, as at. i, the guide fingers or clips I being preferably arranged midway of the length of the side rails.

A third pair of guide fingers or clips J is secured to the bottom rail (Z the same be ing formed of spring metal and provided with slotted portions j for the reception of securing screws j, the same as the fastening arrangement for the devices H, this method. of fastening enabling longitudinal adjustment of the upper and lower fingers, and the same being formed ofspring metal normally tending to spring outwardly from the screen rails to which they are attached, they may be adjusted laterally of the guide rails E through the medium of the screws 7", to create a greater or less frictional binding contact with the guide rails and thus secure a sufiicient gripping of the rails to hold the screen in any position of vertical adjustment. The guide fingers or clips I, J, that is, the projecting portions thereof are turned or deflected outwardly at their upper and lower edges with reference to the adjacent surface of the guide rails for a purpose as will presently appear.

The guide members E have respectively cut-away portions or recesses K, conveniently two, one arranged near the lower end position, the upper and lower edges of the recessed port-ions being beveled or turned inwardly toward the side rails of the screen frame, in other words away from the surface over which the guide fingers or clips ride, so that the clips aided by their special formation will normally ride over the slot ted portion of the guides so that the screen will not become detached, while at the same time the recessed portions are so arranged that the screen may be readily removed therethrough, which is accomplished by raising the screen until the guide clips J register with the lowermost recesses when by an out-ward pressure on the screen frame the clips will be forced through to the opposite sides of the guides, and further raising movement of the screen will bring the mid dle clips I in registration with the upper recesses, when the said middle cllps are forced therethrough and the screen pulled down with the released clips behind the guides until the upper clips comeinto registration with said upper recesses and are released therethrough, the screen frame assuming an inclined position to pass down be yond the sill of the casing to permit the upper clips to move downwardly sufficiently far to pass through said upper recess. The screen is inserted by a reverse operation to that just defined. The screen frame isof course furnished with any desired screen fabric L, such as the conventional wire mesh,

and all of the clips are preferably formed of metal.

From the foregoing description it will be appreciated that by simple, inexpensive means, I have provided a practical screen attachment for windows and one in which the screen may be applied or removed without the necessity-for manipulating locking devices or as stated, in another way, the screen as removed is intact so far as the parts thereof are concerned and remains in the same condition when applied in the window casing without thenecessity of any adjustments whatever, save only as, from time to time, itmay be desirable to regulate the degree of holding friction of the lower clips through the medium of" the adjustment of j the outer fastening screw thereof.

While I have herein disclosed one special embodiment. of the invention, it will be apparent-to persons skilled in the art, thatchanges may be made in the construction and arrangement of parts without departing from the spirit of the invention as may be comprehended in the hereto appended claims.
